我是应用程序见解的新手。

此票证中的详细信息与使用 .NET Framework （而非 Core） 的 C# 编写的特定 API 相关，该 API 在 Windows Server 2012 R2 数据中心虚拟机上的 IIS 中运行。

我们为此 API 提供了许多应用程序见解指标，包括我们自己编写的一些非常有用的自定义遥测数据。

但是一些关键的事情，如每秒的请求数和每秒失败的请求数，并没有通过。

我已经进行了一些挖掘，并在该特定 API 的应用程序见解日志中找到了一些跟踪信息，这些信息看起来可能相关，但我不确定如何处理它们。

下面是一个例子：

AI：收集 3 个已配置的性能计数器时出错。请检查配置。

计数器 \ASP.NET 应用程序（？？APP_W3SVC_PROC？？\请求/秒：无法对性能计数器执行第一次读取。请确保它存在。类别：ASP.NET 应用程序，计数器：请求/秒，实例_LM_W3SVC_4_ROOT

计数器 \ASP.NET 应用程序（？？APP_W3SVC_PROC？？\请求执行时间：无法对性能计数器执行第一次读取。请确保它存在。类别： ASP.NET 应用程序， 计数器： 请求执行时间， 实例_LM_W3SVC_4_ROOT

计数器 \ASP.NET 应用程序（？？APP_W3SVC_PROC？？\应用程序队列中的请求：无法对性能计数器执行第一次读取。请确保它存在。类别： ASP.NET 应用程序， 计数器： 应用程序队列中的请求， 实例_LM_W3SVC_4_ROOT

再比如：

AI：应用程序洞察配置文件加载失败。找不到类型“Microsoft.ApplicationInsights.StatusMonitor.SdkSourceTelemetryInitializer， Microsoft.AI.StatusMonitor”。跳过类型加载。监测将继续进行。

因为我是新手，所以我真的不知道从哪里开始。我尝试在谷歌上搜索错误消息，但我没有想出太多对我目前的情况有用的东西。

任何指向正确方向的指针都非常感谢。
